ROLL-MACHINE FOR REDUCING CEREALS FOR FOOD.

SPECIFICATION forming part of Letters Patent No. 533,551,dated February 5, 1895.-

Application filed April 28, 1894:. Serial No. 509,404. (No model.)

To all whom it may concern.-

Be it known that I, HENRY D. PERKY, a citizen of the United States, and a resident of Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Boll-Machines for Reducing Cereals for Food; and Ido declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a back view of the machine. Fig. 2 is a side view. Fig. 3 isasectional view. Fig. 4: is a top view with the hopper removed.

This invention has for its object to provide a machine for the reduction of cereals and other articles of food, wherein a single grooved roll is employed in conjunction with a stationary or non-reciprocating adjustable back plate.

In the accompanying drawings, the letter A designates a frame having bearings B, for the reducing roll 0, which is designed to rotate upon a horizontal axis, and is circumferentially grooved as indicated. The frame is also provided with bearings D for the pivots E of the back plate E, which is designed to engage the face of the roll C in order to cooperate therewith in reducing the grain which is fed from the hopper G between said roll and the upper extension of flange H, of said plate, and causing the mashed product to enter the grooves of said roll. The back plate is adjustable, its position being governed by the screws 1, which extend through lateral bearings of said back plate into the frame. The adjustment required is very slight, whether it be designed to hold the backplate in contact with the surface of the roll in order to reduce the material to shred-like or filamentous form, or to allow a slight interval between the roll surface and the backplate in order to reduce the material to the form of a ribbon or film having a corrugated surface.

In some cases, it is designed to provide the flange of the back plate with a corrugated feed roll as indicated at J; or the flange may be made to have an oscillating feed motion.

K represents the discharging comb, which is supported upon bearings L of the frame, and extends transversely of the cylinder or roll in front. The contour of its edge is complementary to that of the roll surface which it engages to clear the material from the grooves thereof, discharging the same in thread like or shred form.

In preparing grain for this machine, it should be boiled until sufficiently cooked without destroying the whole form of the grains, and then dried sufficiently to restore somewhat the interior'consistence thereof, and equalize the amount of moisture in the several parts of the berry.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-= 1. In a reducing machine forgrain and other articles of food, the combination with a circumferentially grooved roll, and its discharging comb, of a stationaryback-plate engaging said roll, substantially as specified.

2. In a red ucing machine for grain and other articles of food, the combination with a circumferentially grooved roll and its discharging comb, of an adjustable pivoted bacliplate and the adjusting screws, substantially as specified.

3. A reducing machine for grain and other articles of food having the circumferentially grooved feed roll, the back-plate provided with an upper extension or feed flange, the hopper, and the discharging comb, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
